Placement of antenna
The antenna shall preferably be placed at the edge of the PCB oriented as above. Other placements
and orientations and size of groundplanes are possible, but will affect the performance. Avoid active
components near the antenna.
Placement of GSM module or radio
To avoid losses the module shall be placed as close to the antenna as possible.
Strip line
The strip line must be dimensioned according to your specific PCB. ( see Fig 1). No crossing strip lines
are allowed between the strip line and its ground plane.
Via connections
To avoid spurious effects, via connections must be made to analogue ground.
Component matching
Component values are depending on antenna placement, PCB dimensions and location of other
components.
DC Block
Might be needed depending on RF Module configuration.
Clearance area
Avoid components and parts close to the antenna.
Diversity
The antenna should be arranged to maximise the diversity effect. This could be done by separating the
antennas as far as possible and place them perpendicular to each other.
Note ! Incorrect implementation of the antenna will affect the performance.
